MOTOR-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 740,591, dated October 6, 1903.

Application filed Pebruary25. 1903- Serial No. 145,051. (No model.) I

Pennsylvania,have invented a new and useful Motor-Vehicle, of which specification.

This invention relates to certain improvements in'motor-vehicles.

The principal object of the invention is to provide a novel and powerful form of motorvehicle which may be used for traction purthe following is a poses for hauling cars and the like in mines or other places and which may be employed, in connection with a vehicle-frame of proper size, for use as a motor for street-cars and other vehicles.

A further object of the invention. is to provide a motor-vehicle in which a continuouslyoperated motor 1nechanism turning con-' stantly in one direction may be readily connected to both sets of vehicle-wheels to travel the vehicle in either direction without necessitating the stoppage and reversal of the motor.

A still further object of the invention is to provide a novel form of supporting-frame for the reception and supportof all'of the movable parts and to so construct-and arrange the frame as to provide for the ready assemblement of its parts.

A still further object of the invention is to provide a motor-vehicle" in which all of the movable elements shall be shielded from observation and the entrance'of dirt and dust' prevented.

WVith these and other objects in vie the invention consists in the novel construction and arrangement of parts hereinafter described, and illustrated in'the accompanying drawings and particularlypointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificin g any of the advantages of theinvention.

tratin g the'arrangement of the inclosing casing. Fig. 6 is a sectional elevation through one of the counter-shafts, illustrating the convehicle. Fig. 9 is a side elevation of the mechanism, illustrating the construction and 6 5' arrangement of the gas-engine.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

The general frame of the vehicle or car comprises opposite side members 10, adapted at their opposite ends to interfit with transversely-disposed platform members 11, the members being united by securing-bolts 12.

The platform members '11 are webbed and are. provided with suitable guides for the re ception of draw-heads 13, terminatingin couplings 14 for convenience in connecting the vehicle to a caror cars to be propelled, and 4 the stem of the draw-head is surrounded by opposing springs 15, arranged in the usual manner, the springs taking up any shock which may result from the stopping or start ing of a train of cars.

Between the opposite platform members,

each of which is provided with a transverselydisposed flange 16, Fig. 2, is arranged a bedplate 17 for the reception and support of an engine and the various operating members of the device. tal flooring 18 and is provided with a plurality of spaced Webs 19, the webs being vertically extended near the central portion of the frame and the outer of said webs beingpro- -vided with bearings or pillow-blocks 20for 5 the reception of a shaft 21, which is held in place in the bearing by a cap-piece 22, bolted 4 to the pillow-block, and suitable bearings are also provided in the side plates 10 for the reception of the extreme outer ends of said shaft. 1 oo The bed-plate 17 has a horizon- 9o are recessed to facilitate the introduction of the cap -pieces 22 for the lower shaft.- The several webs of the engine-frame are provided with bearings 25, and the side plates are further provided with bearings for the reception of a crank-sh aft 27, having two sets of cranks 28, each pair of cranks being connected in the usual manner by a wrist-pin 29. At the outer ends of the shaft 27 are balancewheels 30 of the character ordinarily employed in explosive-engines for maintaining the engine at a regular speed while in operation. The shaft 2l is provided with a gear-wheel 31, intermeshin g with a similar gear-wheel 32 on the crank-shaft, and as the latter is rotated by the engines the movement is imparted in an opposite direction to the countershaft 21.

The outer side plates 10' are provided with vertically-disposed guideways 33 for the reception of vertically-movable journal-boxes 34, normally held in depressed position by springs 35, of sufficient strength to support the weight of the vehicle and adapted to yield as the weight alters from increase or decrease of the load or fuel-supply and to prevent jarring due to unevenness in the trackway or road-bed. The journal-boxes 34 receive the end portions of shafts or axles 36 and 37, to each of which is secured two flanged supporting-wheels 38,adapted to a suitable trackway,

and said shafts are further provided with loosely-mounted flanged disks 40, having internal friction-faces adapted to be engaged by friction clutching shoes 41, carried by arcuate arms 42, there being any number of these arms and their size and number being varied in accordance with the size of the vehicle. At one end of each of the arms 42 is pivoted the outer end of a spider 43, having a central hub 44, rigidly secured to the shaft and rotating therewith. On the periphery of the hub 44 is mounted a ring or collar 45, feathered to the hub 44 and free for longitudinal movement thereon. This collar 45 is provided with pivot-ears 46, which are connected by links 47 to pivot-ears 48 at or near the free ends of the arms 42, and when the collar is moved in the direction of the friction-disks the latter will be firmly locked to the shafts.

Each of the friction-disks is provided with peripherally-(1isposed teeth forming sprocketwheels, and for the sake of convenience the sprocket-wheels on the shaft 86 are indicated by reference-numerals 48 and 49, while those on the shaft 37 are designated by referencenumerals 50 and 51.

Each of the collars 45 is provided with an annular groove 52 for the reception of a ring 55, and at the opposite sides of each ring are pins 56, passing through elongated openings in the upper ends of spaced crank-arms 57, and the outer sets of crank-arms are con-- nected for mutual movement by links 58. The crank-arms are rigidly secured to rockshafts 59, having suitable bearings 59 on the bed-plate, and one of said rock-shafts is provided with an operating-crank 60, arranged near one end of the machine within convenient reach of an operators seat 61. The arrangement is such that when the operatinglever is moved in one direction both shafts 59 are moved in the same direction, and the friction-shoes at the right-hand side of the lever will be engaged with their respective disks, while the frictionshoes at the opposite sides will be disengaged, and vice versa.

Secured tothe crank-shaft 27 are the two sprocket-pinions 64 and 65, connected by link belts 64 and O5 to the sprocket'wheels 4S and 50, respectively, and on the lower counter-shaft are secured two sprocket-pinions G6 and 07, connected by link belts 6G and 67, respectively, to the sprocket-Wheels 49 and 51. The motor mechanism, which will be more fully described hereinafter, imparts continuous rotative movement in one direction to the crank-shaft 27, and this movement is imparted at the same or at different speed to the counter-shaft 21 through the connectinggearing 32 and 31. hen the operatinglever is in a vertical or mid position, all of the clutching-disks are disconnected from their respective shafts, but by moving the lever in one direction or the other the clutches and sprocket-wheels at either the right or left hand side of the machine may be positively locked to the shaft and movement imparted positively to both shafts in the desired direction, so that the machine may be propelled with equal facility in both directions. I11 ordinary practice where a continuously-operated motor is revolved in but one direction it is usual to employ the axle or shaft at one end of the vehicle for imparting movement to the latter in one direction, while the reverse movement is accomplished by connecting the shaft or axle at the opposite end to said motor mechanism. This construction is ineffective in some cases inasmuch as the weight of the vehicle is not evenly distributed on both axles and the effective tractive force in one direction will be less than that in the other. In the present case the traction is equal in both directions of movement of the vehicle and is equally effective as a propelling agent for moving in one direction or the other.

The webbed portions of the engine-frame are provided with bolting flanges, to which may be secured the inner ends of the cylinders 24, and these may be of the usual form employed for engines of the two-cycle or fourcycle type. I

The engine is provided with the usual inlet and escape ports, and in Fig. 8 is illustrated the arrangement of the mechanism for operating and controlling the exhaust. In this case the stems 70 of the exhaust-valve are provided with small rollers bearing against cams 71 on a counter-shaft 72, connected by gearing 7 3 to the main crank-shaft and operating at suitable intervals to open the exhaustports of the engine. At a suitable point between the two engines the frame is provided with a vertically-disposed stud 74L,-carrying a horizontal disk 75, which is connected by a rod 76 to one end of a governor-actuated lever 77. The lever is 'fulcrumed at an intermediate point to a bracket 78 and has a bifurcated end portion fitting in a groove 7 9 in. a collar 80, mounted on the crankshaft of the engine and connected to a centrifugal or other form of governor which imparts movement to the collar to an extent depending on the speed of the engine. The disk 7 5 is pivotally connected to the inner ends of a pair of arms 81,having suitable guides at their upper ends, and when the speed of the engine is excessive these arms 81 are projected until their outer ends come into the path of travel of collars 82, secured to the valve-stems 70, and prevent movement of the exhaust-valves until the speed of the engine is reduced.

At the platform at one end of the framework 1 are arranged suitable tanks, one for the reception of gasolene or other hydrocarbon and the other containing air under pressure, the air being forced through thehydrocarbon to form an explosive mixture for the two engines and any suitable form of carbureting apparatus being employed for the purpose, or the tanks may contain a supply of gas under pressure for operating the engines.

The platform at the opposite end of the device serves to contain a quantity of water or other fluid which is circulated in any suitable manner through the water-jackets of the gasen gine cylinders for cooling purposes.

In order to properly protect the parts from the entrance of dirt and dust the whole structure is inclosed by a casing 90, as shown in Fig. 5, and said casing may be formed of thin sheet metal, or the side frames 10 may be continued up.to points above the top of the engine, if desired.

The vehicle may be made of any desired size, and while principally intended for han dling cars in mines and for like purposes it maybe employed for other purposes, such as in street-cars, for roadwork, and the like.
